A new study published this week adds to the emerging evidence linking coffee to lower risk of some cancers, giving coffee lovers another excuse to drink up.
This time, researchers found a lower risk of malignant melanoma in older adults with the highest coffee intake. Melanoma is the fifth most common cancer in the U.S. and the deadliest form of skin cancer, but exposure to ultraviolet radiation (UV) and sunburns are the only key risk factors within your control, according to the National Cancer Institute.
The new study published in the Journal of the National Cancer Institute included nearly 450,000 non-Hispanic white participants. Participants answered questions about their coffee intake and then were followed for an average of 10.5 years to see if they developed a non-invasive melanoma, known as melanoma in situ, or malignant melanoma.
Those with coffee intake of more than 4 cups per day had a 20% lower risk of malignant melanoma compared to non-coffee drinkers. High intake of regular coffee and total caffeine, but not decaffeinated coffee, were also associated with a lower risk of malignant melanoma. There was no link between coffee intake and melanoma in situ. Read more… “Study: Coffee Lowers Risk of Deadly Skin Cancer”
Here at AICR, we’re well versed in the latest scientific evidence on food, drink, and cancer prevention. We also know that a lot of people get their health information online, where it can be difficult to separate fact from fiction. So what were we searching for this year, when it comes to cancer and foods and drinks? We used the 2014 Google Trends to find out.
Alcohol and cancer
This was the most popular search term involving cancer and a specific food or drink, for good reason. The latest research has found that alcohol increases the risk of some cancers, including breast and colorectal. Based on the evidence, AICR recommends that if you do drink alcohol, limit your drinks to 1 per day for women or 2 per day for men.
A recent analysis on coffee possibly protecting against liver cancer has nudged its way into the headlines today, adding to the good news for coffee lovers.
Last month, AICR’s continuous update report on endometrial cancer found that coffee protected against this cancer. It was a modest reduction – 7 percent lower for that first cup of coffee. But it was the first time there was enough evidence for AICR to conclude that coffee reduced the risk of a cancer.
Study researchers looked for all relevant human studies between 1966 and 2012, ending up with 16. Analyzed together, drinking any amount of coffee linked to a 40 percent lower risk of liver cancer compared to those who did not drink. Higher amounts linked to lower risk.
